Abstract
The glymphatic system is a brain-wide waste clearance mechanism that mimics lymphatic functions and facilitates the removal of amyloid aggregates. It is supposed to be essential for maintaining homeostasis within the central nervous system including nutrient delivery, waste removal, and consistency of the ionic microenvironment. While its dysfunction has been implicated in a variety of neurodegenerative disorders, its neurovascular implications are only slowly emerging. Driven by arterial pulsatility synchronized with the cardiac cycle, the system promotes cerebrospinal fluid (CSF) influx through perivascular spaces, modulated by aquaporin-4 channels in astrocytes. Waste-laden fluid then drains via perivenous spaces to meningeal lymphatics and cervical lymph nodes. Dysfunctions in this system have been implicated in neurovascular conditions, including subarachnoid hemorrhage, idiopathic intracranial hypertension, steno-occlusive disease, and arteriovenous shunting disorders. These diseases disrupt glymphatic flow through altered pulsatility, impaired CSF influx, aquaporin-4 malfunction, or venous hypertension. Such impairments lead to waste accumulation, contributing to progressive cognitive decline, which may be reversible with targeted interventions. This review underscores the role of the glymphatic system in neurovascular diseases and highlights potential endovascular avenues to mitigate cognitive impairment due to an impaired glymphatic system.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
